1. Number of people eating bug(driven by mimesis pushed through a media narrative and thus typically viral(often exponential).
2. Number of variety of bugs being eaten(regionality and entrepreneurialism((often referred to as Cambrian explosions in perfectly competitive markets, thus exhibiting exponential growth functions)).
3. Number of geographies bugs for consumption being grown in.
4. Number of production methods and processes.
5. New combinations of genetics of peoples and insects/infectious organisms being consumed. Think Montezuma's revenge or lactose intolerance in certain regions of the world except possibly contagious and deadly
Multiply all that by orders of magnitude faster gestation cycle and thus the chance for mutation, aside from technology developed to support existing food chain, Number of mutations per lifecycle, increasing the chances of deadly DNA combination by 12x, so order of magnitude.
Average lifespan of... A. Bacteria: 12 hours B. Insect: 12 months C. Mammal: 12 years (shortest being the primary disease harbinger, the rat).
> At least 2 billion people globally eat insects in over 113 entomophageous countries though this habit is regarded negatively or as revolting by others [4–6]. More than 1900 species are consumed by local populations globally but insect consumption (entomophagy) shows an unequal distribution.
There's roughly 8 billion people on the globe. Between 2 billion to 8 billion, there's not much room left for exponential growth.
